Taxis - Airport
Government taxis are located at the airport, and you can buy tickets for them at the booth just beyond the timeshare area. The rates are quite a bit higher than those of city taxis, usually comparable to a private transfer.
Some people will drag their luggage outside the airport and over the bridge to the city taxi stand, which is a little bit cheaper, but not much, and most people consider it worth the few extra pesos for the convenience of loading in the bags right at the airport.
